Problem Title:
XABEL 5.1 (BLIFOPTX) fails on Truth Table designs


Problem Description:
ERROR MESSAGE:

     *** ABL2XNF: Error
	  ABL2XNF is terminating abnormally due to errors encountered in
	  the blifoptx.exe xffast.bl0 -o xfffast.bl1 -errlog err.err
	  subtool

No .err file gets created.

DESCRIPTION:

This can be caused by a bug in blifoptix .  When there are designs that
have truth tables in which rows can not be optimized,  blifoptx fails
with this error message.


Solution 1:

The only work around is to enter the design as equations instead of
as a truth table.
